Abstract

A method of halogenating thermoplastic polyolefin materials, comprising mixing a thermoplastic polyolefin in particulate form with particulate filler type material in an atmosphere comprising vaporous halogen and in progressive sequence, melting the surface portions of the particles of thermoplastic polyolefin, reacting the halogen with the molten surface portions of the polyolefin particles while combining filler with said molten surface portions, and removing the resulting halogen reacted melt which has been combined with filler from the underlying thermoplastic polyolefin material of the particles. The mixing and melting, halogenating, and the combining and removing of the combined components, are each continued until the desired extent of halogenation of the polyolefin is achieved, and can be carried to the substantial complete diminution of the particles of polyolefin material whereby the polyolefin material is substantially uniformly halogenated throughout its mass.
